PLUMBERS TACK.

SPECIFICATION-forming part of Letters Patent No. 508,822, dated November14, 1893.

Application filed October 20, 1892. Serial No. 449,448. (No model.)

To all whom it may concern: 7

Be it known that I,W1LLIAM, H. EVORY, of Brooklyn, in the county ofKings and State of New York, have invented a new and Improved PlumbersTack, of which the following .is a full, clear, and exact description.

My invention relates to improvements in plumbers tacks such as are usedto support pipes upon the side of a wall.

The object of my invention is to produce a tack of this descriptionwhich may be quickly and firmly clasped around pipes of different sizes,and which also may be easily and securely fastened to a wall so as tohold the pipe to which it is attached in a secure manner.

7 To this end my invention consists in certain features of constructionand combinations of the same, aswill be hereinafter described andclaimed.

Referenceis to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a'front elevation of the tack embodying my invention showingit applied to a pipe. Fig. 2 is a rear elevation of the same with partsin section, showing also the arraf ge- 1g. 3 is a cross section throughthe tack and pipe on the line 33 in Fig. 1. Fig. 4 is a cross section ofa modified form of tack, showing it applied to a pipe; and Fig. 5 is across section of another modified form which is adapted for use insupporting two pipes.

The tack comprises two oppositely arranged leaves which have convexinner portions 10 adapted to fit upon a pipe, and whichhave alsodepending flanges 11 at the edges so as to form each leaf into a sort ofcase adapted to contain the adjusting rod or the holding bands, ashereinafter described. Each leaf is also provided with holes 12 inwhichthe fasrtening screws 13 are inserted to attach the tack to the wall.The two leaves are connected on their outer sides by bands 14 whichextend through, openings 15 in the leaves and which are, adapted toextend around a pipe and clamp it firmly in place. The bands at one endare rigidly secured to one of the leaves 10, as shown at 16 in Figs. 2and 3, and. the opposite ends of the bands are attached at 17, to asplit rod, or shaft 18. The bands 14 are made preferably of springmaterial and i the tension of the coil is usually enough to fasten apipe. The split rod or shaft turns in bearings 19 and the rod may beturned so as to tighten the bands 14 by winding them upon site the endsof the rod or shaft, as shown at 20 in Fig. 2', so as to permittheapplication of the key. It will be seen, that by the rotatable shaft,the bands may be taken up or shortened to any desired extent, '6. a,unlimitedly to adapt them to clamp any size of pipe. When the shafts,18, are turned to tightenthe bands, 14, the strain on the latter tendsto separate the members of the shafts, so that the latter bind'in theirsockets, or bearings, and thus retain their positions and hold the bandsunder strain to the required degree.

The bands 14 are adapted to extend around a pipe 22 and after they arepassed'around the pipe the leaves are held together behind the pipe by abook 23 which is secured to one of the leaves 10 near one edge, as shownat 24, and which at its free end is adapted to engage a slot 25 in theopposite leaf, asshown clearly in Figs. 2 and 3.

Inapplying the tack to a pipe one of the leaves is passed over the pipe,after which the hook 23 is made to engage a slot 25, and the pliabilityof the bands 14 permits this to be easily done. After the leaves areapplied and fastened together they are secured to the wall by means ofscrews and the pipe is thus held in place. In Fig. 4 I have shown a formof tack which is on the same principle as the form already described,but which is adapted to be applied and fastened on one side of the pipe,as certain positions in buildings are such that two leaves cannot beconveniently ap plied. Here the leaf 10 is like one of the leavesalready described, with certain slight modifications which will bedescribed below. The leaf is provided with the bands 14 and with a shaft18, like that already described, to which the bands are fastened at oneend. The opposite ends of the bands are fastened to a supplemental leaf27, as shown at 26, which leaf is arranged to swing within the leaf 10and is hinged to the inner portion of the leaf, as shown at 28. The freeend of the leaf 27 is adapted to be held within the leaf 10 by aspringcatch 29, and the leaf has perforations 30 opposite the perforations 12in the leaf 10, so that the fastening screws may pass through bothleaves. The hinge at 28 is formed by simply engaging pintles on the leaf27 with recesses in the leaf 10, as shown clearly in Fig. 4, but anyother kind of detachable hinge may be used.

It will be seen, that in both forms of tack the two members, or leavesare held detachably connected by certain means so that they may beeasily separated when required.

I 5 In applying this tack the leaf 27 is passed around the pipe 22,taking the band 14 with it, after which the leaf is hinged to the leaf10 and forced upward into the same, as shown in Fig. 4, when the wholetack is in position to be screwed to the wall. The form of tack shown inFig. 5 is adapted to fasten two pipes together and illustrates the factthat the tack may be made to fasten any number of pipes. Here the leaves10 are each provided with :5 split shafts'18 to which the bands 14 aresecured, as already described, and a center-piece 31 is interposedbetween the leaves and hinged to one of them, as shown at 32, this piecehaving a central rib 33 which extends between the two pipes 22 which arefastened by the tack, and the walls of the center piece diverge andcurve so as to form practically continuations of the curved surfaces 10of the leaves 10. The free edge of the center piece is pro vided with ahook 23 which is fastened to one 35 of the leaves 10 in the manneralready described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A pluinbers tack comprising two separable leavesadapted to be secured to a wall, pipe bands which are attached at oneend to one of said leaves, and a rotatable shaft jour naled in-the otherleaf and to which the other ends of the bands are detachably connected,and around which they are wound, unlimitedly, for clamping any size ofpipe, as shown and described.

2. A plumbers tack comprising two sepa- 5o rable leaves adapted to besecured to a wall,

a catch holding the said leaves connected, and bands attached to-one ofthe leaves and to a rotatable shaft journaled in the other leaf, asshown and described.

3. In a plumbers tack, the combination, with a recessed leaf, ormember,-adapted to support a pipe and for attachment to a-wall, of asupplemental leaf, or member, 27, adapted to be held in the recess inthe other leaf, means for holding the supplemental leaf de: tachably inplace, and pipe-clampingbands, and a rotatable shaft for taking up thebands, as shown and described.
